Abstract
The present invention discloses the use of gold oxide as a catalyst for use in a hydrogen sulfide gas detector. The gold oxide catalytic surface being supported on an electrically conductive substrate; thereby allowing the flow of electrons between the anode and the cathode to occur between the substrates of the electrodes instead of the catalytic surfaces. This will reduce the amount of catalytic material required to form the electrode, and will not require that the catalytic surface be an electrical continuum.
